Description:

Juventae Chasma is an enormous box canyon (250&nbsp;km × 100&nbsp;km) on Mars which opens to the north and forms the outflow channel Maja Valles.

Juventae Chasma is located north of Valles Marineris and cuts more than 5&nbsp;km into the plains of Lunae Planum. The floor of Juventae Chasma is partly covered by sand dunes. There is also a 2.5&nbsp;km high mountain inside Juventae, 59&nbsp;km long and 23&nbsp;km wide, that was confirmed by Mars Express to be composed of sulfate deposits. MRO discovered sulfates, hydrated sulfates, and iron oxides in Juventae Chasma.
